Fig. 4
Interaction and temperature dependence of the dimensionless resistivity ρ. These data correspond to those shown in Figs. 3 and 5. a Interaction scaling, fit (solid line) fit to DMFT scaling law U2 with reduced χ2 = 0.99. b Temperature scaling, fit (solid line) to DMFT scaling law T with reduced χ2 = 1.76. The vertical error bars include the uncertainty in the fit used to determine τt and the uncertainty in ndwd from the measurements of N and T. Orthogonal distance regression is used for fitting to accommodate the horizontal error bars in b. The plots along the right side of the figure show the local spectral function A(ω) using a constant vertical scale, and the energy ω relative to the Fermi energy is in units of the half bandwidth W. A(ω) is calculated at U/t = 2.3 for b. The inset in b shows the ratio between the dimensionless resistivity and the MIR limit
